lNCLlNED-WHEEL EARTH-EXCAVATOR.

SPECIFIGATION forming part of Letters Patent No. 335,229, dated February2, 1886.

Application filed March 37, 1885.

To all whom, it may (lo/warn:

Be it known that l, SAMUEL M. Looxwoon, a citizen of the-United States,residing at New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements inInclined-\Vheel Earth-Excavators; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

The object of this machine is to excavate earth.

Figure 1 is a perspective view of the entire machine. Fig. 2 is acrosssection taken through line m m on Fig. 1. Fig. 3 represents a planview of the frame, showing the brake. Fig. 4 represents an enlarged viewof latch, trigger, and earth-gate.

A is the inclined wheel, which may be of any diameter-probably mostconveniently twelve feet in a wheel that is to be used in connectionwith carts or cars. The dirt is carried on the rim B of the wheel A,which rim may be of any width. For a twelve-foot wheel fourteen orsixteen inches would be a proper width for said rim. The said rim is tobe dished or beveled, like the rim of an ordinary table-plate, in orderthat it may lie flat where it rests on the ground. The inside of thisrim consists of gates C. There should be one gate between each pair ofspokes D of the inclined wheeh About nine spokes should be in theinclined wheel, although any number may be used. A convenient number ofgates also is nine to each machine. The gates may be of any width. Aconvenient width is twelve or fourteen inches. The gates are hung byhinges \V at the top of the gate, and are connected with arms E, at ornear the outer end of arms, said arms running from the hub of inclinedwheel to the gates, said arms to be fastened to the spokes by bolts orin any other manner at the point where they intersect said spokes, forthe purpose of strengthening the machine. The gates have latches F,running from about the center of the gates. These latches may be of anylength, a convenient length being about four feet, and may be of anysize, according to the material used. The latches run from the gates tothe circle G, and catch on said circle. Said circle may be of anymaterial, may

be of any size, a convenient size being about from one to twoinchesthick, and may be about two feet distant from the hub and resting onspokes of wheel A. From the top of axle ll. of inclined wheel an arm,It, is extended toward the latch, with a piece, I, across the end ofsaid arm. Said piece may be ofany desired thickness at the center,tapering down to the ends of the same, so that the latches rising overthe center of the same are lifted high enough to take them oif of theaforesaid circle, and thus the gates or doors are let down and the earthis dumped.

The hub J of inclined wheel may be forty inches (more or less) inlength, and larger or smaller in size, according to material used inconstruction of the same. If made of wood, it should be a foot or morein thickness. Any material may be used in the construction of themachine.

Underneath the inclined wheel is a supporting-wheel, K, which may be ofany convenient size to carry the inclined wheel at an angle of aboutthirty degrees, more or less. Said wheel should have a wide tire, andmay be constructed similarly to an ordinary cart-wheel,

but must be heavy enough to carry the inclined wheel when the same bearson it, one side of the inclined wheel resting on the ground.

The frame L is supported on the side toward the supporting-wheel on theaxle of said supporting-wheel, which axle H is crooked, so as to extendthrough the hub of the inclined wheel, and also form the axle of theinclined wheel. Frame L is supported on the side toward the plow P bymeans of arms or braces S, extend ing from the axle of the inclinedWheel above the hub of said wheel to said frame, as set forth in thedrawings. Said frame is connected at the ends by cross-pieces M.

To retard motion and to prevent the machine from rotating toward theplow, a brake, N, is connected with the frameL, running parallel withthe frame. It may run around either the front or the rear end of frame.Around the rear will be most convenient. It may be on the top of frameor underneath the frame. Underneath will be most convenient. Said brakemust extend to the supporting-wheel and act on said supporting-wheel.The lever by means of which the brake is operated should be on the sidenext the plow, and where it can be reached by the man driving or the manplowing.

The machine is moved by the team attached to the tongue T, which may besimilar to a 5 wagon-tongue, but should be stronger, and

must be a stiff tongue.

P is an ordinary plow attached to the frame, the object of which is tothrow the dirt on the inclined wheel.

10 The machine may be worked with two teams of oxen or horses or anyother power, and needs two men to handle it-0ne to handle the plow andthe other to manage the teams. The machine itself is automatic.

15 As the machine is drawn forward, the illclined wheel revolves on itsaxis, and thus the earth is carried to the depositingplace at the top ofinclined wheel.

The parts R and Iare described as the trig 2o ger in the specification.By removing the trigger entirely from the machine the machine can beused as a selfloading cart.

I claim- 1. The combination, with an inclined-wheel 2 5 excavator andits plow, of the frame, and the stiff tongue, and thesupporting-wheel,and the crooked axle forming an axle for both wheels,and a brake adapted to be applied to the sup porting-wheel,substantially as and for the purposes set forth. o

2. The described self-adjusting latches and dirt-gates, and the circleon which the latches are fastened or caught, and the mechanism forworking the same.

3. The combination, with an inclined-wheel 3 5 excavator, of a brakeapplied to the supportlug-wheel. 1

4. The combination, with an inclined-wheel excavator, of a stiff tongue,which tongue is attached directly to the frame and may form 0 part ofthe frame, as in the drawings, which frame runs continuously around theentire machine, and which frame is no part of plowbeam, nor is plow-beampart of it.

In testimony whereof I affix my signature in ,4 5 presence of twowitnesses.
